I brought Charlie home 2 weeks ago now, and have slowly been changing his food to Purina One Growth and Development. When i first brought him home my husband and I thought he never even went poop and we were a little concerned. After some dedective work and dog spying we figured out he was eating it! Now that we've fully changed his food he doesn't even look twice at it. He just does his business and leaves it be. FYI the breeder I got him from was feeding him Eukanuba. I say, if you're puppy is eating the poo- try switching the food. Maybe it's either so darn tasty he just can't get enough
or it's lacking in some serious nutrients.
